Problem 47

Spanking In March 1995, The Harris Poll reported that 80% of parents spank their children. Suppose a recent poll of 1030 adult Americans with children finds that 781 indicated that they spank their children. If we assume parents’ attitude toward spanking has not changed since 1995, how many of the 1030 parents surveyed would we expect to spank? Do the results of the survey suggest that parents’ attitude toward spanking may have changed since 1995? Why?

Step-by-Step Solution:

Step 1 of 5) Spanking In March 1995, The Harris Poll reported that 80% of parents spank their children. Suppose a recent poll of 1030 adult Americans with children finds that 781 indicated that they spank their children. If we assume parents’ attitude toward spanking has not changed since 1995, how many of the 1030 parents surveyed would we expect to spank Do the results of the survey suggest that parents’ attitude toward spanking may have changed since 1995 Why Objective. Determine the appropriate hypothesis test to perform Determine the Appropriate Hypothesis Test to Perform Perhaps the most difficult aspect of testing hypotheses is determining which hypothesis test to conduct. To assist in the decision making, we present Figure 24, which shows which approach to take in testing hypotheses for the three parameters discussed in this chapter. Preparing for This Section Before getting started, review the following: Computing normal probabilities (Section 7.2, pp. 366–370).
